One end of ideal string tied up with fixed suppot & other end is tied with a bob. The string is released from horizontal position. When string makes an angle of `theta` with vertically downward direction then the acceleration vector of bob is horizontal then `theta` is

A simple pendulum is released from rest at the horizontally stretched position. When the string makes an angle theta with the vertical, the angle theta which the acceleration vector of the bob makes with the string is given by–

A bob of mass 1 kg is suspended from an inextensible string of length 1 m. When the string makes an angle 60^(@) with vertical, speed of the bob is 4 m/s Net acceleration of the bob at this instant is

A bob of mass 1 kg is suspended from an inextensible string of length 1 m. When the string makes an angle 60^(@) with vertical, speed of the bob is 4 m/s Net acceleration of the bob at this instant is

A coical pendulum consists of a string of length L whose upper end is fixed and another end is tied to a bob. The bob is moving in horizontal circle with constant angular speed omega such that the string makes a constant angle theta with the verticle. calculate time period T_(0) of revolution of bob in terms of L,g and theta .

A stone tied to a string of length l is whirled in a horizontal circle at a constant angular speed omega in a circle of radius r. If the string makes an angle theta with vertical then the tension in the string is :

A stone tied to a string of length l is whirled in a horizontal circle at a constant angular speed omega in a circle of radius r. If the string makes an angle theta with vertical then the tension in the string is :

In a simple pendulum, the breaking strength of the string is double the weight of the bob. The bob is released from rest when the string is horizontal. The string breaks when it makes an angle theta with the vertical.

In a simple pendulum, the breaking strength of the string is double the weight of the bob. The bob is released from rest when the string is horizontal. The string breaks when it makes an angle theta with the vertical.

One end of a string of length L and cross sectional area A is fixed to a support and the other end is fixed to a bob of mas m. The bob is revolved in a horizontal circle of radius r with an angular velocity omega such that the string makes an angle theta with the vertical. Young's modulus is Y. The tension T in the string is
